i have personally never heard of a grinding catalytic. also, these vehicles are not known for cat failures (not to say it can't happen). my first suspicion would be a faulty wheel bearings or lumpy tire. next time you are driving, try swerving the car side to side and listen for if the tone of the noise slightly changes. if so, you can bet you have a bad bearing. i would get a second opinion on the noise, the best way to check and isolate a bearing noise is to put the car on a hoist and accelerate to the speed of the noise, with someone underneath using a stethescope probe to isolate the source of the noise. if the noise goes away on the hoist, you can bet its a tire noise. good luck!

The transmission has cooler lines that run to and from the radiator. The fluid is cooled, by running thru tubing inside the one side of the radiator tank. The tubing probably has a leak, causing anti-freeze to get into the transmission. This MUST be repaired, due to the fact that the anti-freeze will do some damage to the transmission.

It depends on which "service" light you are talking about. "Service Engine"? "Service Vehicle"? In any case, you must scan your onboard computer network to find out why the light has been turned on. Then, any necessary repairs need to be made before clearing any fault codes in the system. Otherwise, the light will just come back on again.
